SPRING BED-BOTTOM.

SPECIFICATION forming part of Letters Patent No. 556,923, dated March24, 1896. Application flied June 24, 1895. Serial No. 553,814. (Nomodel.)

To LZZ whom it may concern:

Be it known that we, FRANKLrN L. Gnorr and FRANK D. OOLVIN, citizens ofthe United States, residing at Baltimore, in the State of Maryland, haveinvented certain new and useful improvements in Spring Bed-Bottoms; andwe do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

Our invention relates to improvements in bed-bottoms, and particularlyto that class thereof wherein the same consists of a metal framedesigned to be seated in the bedstead and a webbing of coiled-wirestrands. Heretofore in this class of bedbottoms the same have been opento objection for the reason that it was the common practice to twistsaid ends over the end bars, and this was objectionable in that the saidwire ends offered numerous points with which the ticking of the mattresswould engage as well as the bedclothing and thereby become torn andinjured.

The objects of our invention are to overcome these serious objections byguarding or covering all wire ends and to accomplish this in a simpleand convenient manner and so as not to increase the cost of constructionto an appreciable extent, and, furthermore, to render more rigid themetal frame.

Vith these objects in view the invention consists in the features ofconstruction hereinafter specified and particularly pointed out in theclaims.

Referring to the drawings, Figure 1 is a plan view of a bed-bottomconstructed in ac cord ance with our invention, a portion of one of theguards being broken away. Fig. 2 is a transverse sectional View throughone of the end bars and guards.

Like numerals of reference indicate like parts in both the figures ofthe drawings.

In practicing our invention we produce the usual bed-bottom frame ofsuitable gage Wi re and in a continuous manner, the aforesaid frameconsisting of the opposite longitudinal side bars 1. and the end bars 2.The Wire blank from which the frame is produced has its ends connectedwithin one of the cross or end bars by a metal sleeve 1Within this frameis woven the usual webbing 4, the same consisting of a series ofinterlocking coils of Wire. The usual practice of securing the coilsover the end bars is here carried out, the same con sisting in givingthe ends of each adjacent pair of coils a twist, as indicated at 5. Thisleaves the series of exposed wire ends heretofore stated as beingobjectionable. Over each of the end bars is introduced a U -shapedsheet-metal guard G, the same being of such length as to agree with theend bars, and after being put in position bythe use of a suitable handtool the terminals of the U shaped guard are closed or nearly so, so asto inclose the cross-bar to which it is applied and in doing so coverfrom view the ends of the wire coils. It will thus be seen that not onlyare the ends of the wire coils efliciently covered and engagementtherewith of any of the bedclothing positively prevented, but also thebed-bottom fram e itself is materially strengthcned and made rigid,which is a desirable and material obj ect.

The meeting edges of the guards clamp upon the coils of Wire and alsoserve to strengthen the fastenings between the eoils'of wire and the endbars of the frame.

Around the guards and to the side bars of the bed-frame coils S, eachconsisting of one or more strands of wire, are passed, and each coilengages with an adjacent coil of the Woven wire bottom, and in thismanner the bed-bottom as a Whole is secured in position. The meetingends of these side or end coils are also introduced within the guard, sothat when the bed is complete nothing in the way of projecting ends ofwire is to be met with.

From the foregoing it will be seen that we have produced a bed-bottom ofthe class specified wherein a smooth, unbroken, and uninterruptedsurface is presented to view and wherein the same is totally devoid ofpointed or other projections that are capable of in any way offeringinjury to the bed ticking or clothing.

Having described our invention, what we claim is l. In a bed-bottom, thecombination with a rectangular frame and the inclosed wovenwire bottom,the ends of Whose coils receive the end bars of the frame and aretwisted therebeyond, of the sheet-metal tubular guards inclosing thetwisted ends of the coils and end bars of theffrarnefsaid guards beingopen at one sideto receivethe woven-wire bottom, substantially asspecified.

2. In a bed-bottom, the combination with a rectangular frame and theinclosed Wovenwire bottom,` the ends of Whose coils receive the end barsof the frame and are twisted therebeyond7 of the sheet-metal tubularguards inclosing the twisted ends of the coils and end bars of theframe, said guards being open at one side to receive the wovenwirebottoni,V

and means for securing the guards in their clamped position,substantially as specified.

3. In a bed-bottom the combination with a rectangular bed-frame and theinclosed woven-wire bottom, the ends of the coils of tures in presenceof two witnesses.
